THE PROJECT WILL DEVELOP AND TEST A HARDENED GUNN VOLTAGE CONTROLLED OSCILLATOR (VCO) CAPABLE OF SURVIVAL TO A LEVEL OF AT LEAST 50,000 G WITH A GOAL OF 100,000 G. SUCH AN OSCILLATOR HAS POTENTIAL APPLICATIONS TO PROJECTILES OR MISSILES WHICH EXPERIENCE VERY HIGH SHOCK DURING FIRING (LAUNCH). THE DESIGN INVOLVES USE OF A RIGID CHOKE STRUCTURE WHICH PREVENTS TOP LOADING ON THE GUNN AND VARACTOR DIO ...

THE GLOBAL POSITIONING SYSTEM (GPS) SATELLITES TRANSMIT INFORMATION ON TWO FREQUENCIES IN THE L-BAND: L(1) AT 1575.42 MHZ AND L(2) AT 1227.6 MHZ. THESE TWO TRANSMISSIONS ARE PHASE-COHERENT SINCE THEY ARE DERIVED FROM A COMMON OSCILLATOR. BOTH OF THESE FREQUENCIES ARE MODULATED BY A P-CODE CONSISTING OF PSEUDO-RADOM ONE'S AND ZERO'S. THE TRANSMISSION RATE IS 10.23 MHZ AND THE CODE ON BOTH THE TRANS ...

WE PROPOSE THE DEVELOPMENT OF A COMPUTER-BASED INTELLIGENT INSTRUCTIONAL DESIGN SYSTEM (IIDS) THAT WILL ACT AS AN ADVISOR TO THE INSTRUCTIONAL DESIGNER CONCERNING EDUCATIONAL THEORY AND PRINCIPLES. THE IIDS WILL BE BASED ON CONTEMPORARY COGNITIVE AND INSTRUCTIONAL SCIENCE PRINCIPLES AND WILL TAKE ADVANTAGE OF CURRENT TECHNOLOGIES WITHIN THE FIELD OF ARTIFICIAL INTELLIGENCE. THE IIDS WILL BE A STRU ...

REDUCTION OF SATELLITE RADIANCE DATA TO TEMPERATURE PROFILES INVOLVES BOTH DIFFICULT MATHEMATICAL INVERSION ANALYSIS AS WELL AS COMPLICATED DATA PROCESSING. RECENTLY, THE APPLICATION OF THE OPTICAL MEASURE THEORY REPRESENTS A NOVEL APPROACH WHICH PROVIDE A SOLUTION FREE FROM THE NEED OF EXTERNALLY-IMPOSED CONSTRAINTS (KING, 1987). THE OBJECTIVE OF THIS PROPOSAL IS TO DEVELOP A SYSTEMATIC TECHNICAL ...

A CONCEPT FOR A WIRELESS V-BAND COMMAND/RESPONSE DATA LINK IS DESCRIBED WHICH WOULD HAVE MAJOR IMPACT ON COMMUNICATIONS IN AIRCRAFT AND SUPPORT ELECTRONICS SUBSYSTEMS (INCLUDING MISSILES AND SUBMUNITIONS). THE WIRELESS LINK CAN BE USED TO REPLACE HARD-WIRE CABLES OR DATA BUS (TO SAVE WEIGHT AND WEAPONS RELIABILITY) AND/OR AS A REDUNDANT BACKUP TO WEAPON AIRCRAFT SURVIVABILITY IN EVENT OF BATTLE DA ...

RESEARCH WILL BE CARRIED OUT TO DEMONSTRATE THE UNIQUE VALUE OF CHEMICALLY BONDED CERAMICS (CBC) AS MATERIALS FOR FABRICATION OF MECHANICAL DETERRENTS TO SYMPATHETIC DETONATION OF MUNITIONS. CBC MATERIALS WILL BE FORMULATED AND CHARACTERIZED FOR SHOCK ATTENUATING PROPERTIES AND FRAGMENT CAPTURE OR VELOCITY REDUCTION PROPERTIES. THE FINAL MATERIAL IS LIKELY TO BE A BINARY MATERIAL (TWO DIFFERENT TY ...

IN THIS PROPOSE PHASE I SBIR DESIGN EFFORT, WE WILL DESIGN A PORTABLE, MULTICHANNEL, BATTERY-OPERATED DEVICE THAT WILL DIGITIZE, PROCESS, AND STORE PHYSIOLOGICAL DATA. IT WILL OPERATE IN FLIGHT UNDER HIGH LEVELS OF G STRESS. THE PROGRAMMABLE DEVICE WILL BE CAPABLE OF ACQUIRING DATA AT RATES SUFFICIENT TO RECORD EEG AND ECG WAVEFORMS. THROUGH THE USE OF DATA COMPRESSION TECHNIQUES, IT WILL ALLOW DA ...

A NOVEL AND INNOVATIVE APPLICATION OF AN EXPERT KNOWLEDGE-BASED SYSTEM (KBS) TO SPACE SYSTEMS IS PROPOSED. A KBS DESIGN CONCEPT WILL BE DEVELOPED TO AUTONOMOUSLY MANAGE AND OPERATE SPACE GROUND SUPPORT SYSTEMS. IN PHASE I, THE KBS DESIGN WILL BE EVALUATED AS A TOOL IN INCREASING EFFICIENCY, RELIABILITY, MISSION SUCCESS, AND SAFETY; TO REDUCE COSTS OF MANAGEMENT, DESIFN INTEGRATION AND TEST; AND TO ...

FOR A CONE-SHAPED REENTRY VEHICLE, THE ANTENNA WINDOWS CAN BE THE NUMBER ONE CONTRIBUTOR TO THE VEHICLE'S RADAR SIGNATURE AT CERTAIN RESONNANCE FREQUENCIES. WE PROPOSE TO DEVELOP A COMPUTER MODEL FOR PREDICTING THE RADAR-CROSS-SECTION (RCS) OF THE ANTENNA WINDOW BASED ON AN EXACT MODE MATCHING TECHNIQUE IN ELECTROMAGNETIC THEORY. IN PHASE II, THIS CODE IS TO BE EXPANDED SO THAT THE RCS OF THE ENTI ...
